Rotary table for testing projectile wing deployment under the condition of multi-angle high-speed rotation of projectile body

Abstract

The invention relates to a rotating platform for testing the unfolding of a missile wing under a multi-angle high-speed rotating condition of a missile body, and belongs to the field of high-speed rotating platform experimental research designs. According to the rotating platform, the angle of a work piece is regulated by adopting a motor screw rod transmission mechanism; a motor shaft and a work piece rotating shaft adopt an integrated shafting design; the defect of rotating speed loss during a commonly used belt transmission process is eliminated; a transmission structure is simplified; the stability is improved; the overall structural integration is realized. The missile body is fixed at the two ends and is connected through a bracket, so that the missile body can be ensured to rotate at a high speed. In addition, the rotating speed can also be used for researching the high-speed rotating characteristics of the missile bodies with different sizes through simple transformation. A missile wing unfolding testing device is arranged on a rotating bracket; the unfolding and locking conditions of the missile wing can be represented through the movement of a fixed pin. To sum up, the rotating platform provides a safe and reliable research platform for researching the high-speed rotating characteristics of the missile body at different angles and testing the unfolding and locking of the missile wing, so that the rotating platform has a very good use value.

Description

technical field [0001] The invention relates to a rotary table used for testing the deployment of projectile wings under the condition of multi-angle high-speed rotation of projectile bodies, in particular to the research on the rotation characteristics of projectile bodies at different angles, and belongs to the field of experimental research and design of high-speed rotary platforms. Background technique [0002] Rotary missiles are a type of small missiles with simple system, low cost and high reliability. This type of missile was first adopted by most anti-tank missiles. With the development of missiles, especially tactical missiles, in the direction of miniaturization, automation, autonomy, and ammunition, many small air defense missiles, especially portable missiles, have gradually chosen rotary bombs. It is closed inside the projectile body, and the projectile wings are unfolded by the internal ejection device after receiving the trigger signal. Rotating missiles oft...
